recycling drilling fluid Articles

Drilling fluid additives and the water that contains them are an essential part and expense of successfully completing a horizontal directional drilling (HDD) installation, and the longer the bore and larger the product being installed, the more drilling fluids cost. Therefore, it makes economic sense to recycle drilling fluids by removing cuttings and recirculating the cleaned ...

At present, environmental protection is a basic state policy in China, and it has been a strategic mission and goal for our country to maintain a sustainable development of society, economy and environment. Along with the continuous improvement of environmental laws and the increasing environmental awareness among people, the departments concerned have successively enacted various environmental ...

Effective & fast mud cleaning for the oilfield. SAS microemulsion drilling mud cleaning products speed up the cleaning and removal of drilling mud waste. The cleaning of drilling mud residues from mud pits, offshore supply vessels and mud trucks is traditionally a time consuming task. Using high pressure water or standard cleaning detergents usually results in large volumes of mud slop ...

Grangemouth based Surface Active Solutions (SAS) has developed its microemulsion based technology to aid the prevention and management of drilling waste. The many activities surrounding the removal of drilling mud in surface and downhole cleaning applications usually generate significant volumes of oil contaminated drilling waste. The drilling mud is typically removed through the use of solvents ...

Relative to the use of drilling fluids within the oil & gas industry, the use of drilling fluids within the horizontal directional drilling (“HDD”) industry, is new. As the use of HDD technology did not become mainstream until the 1980’s, it took another decade before drillers started to consider the use of basic drilling fluids. Even today, ...

It is generally recognised that the sustainability concept integrates economic, environmental and social aspects. It would be interesting for manufacturers to be able to know which process, workpiece materials or machining condition is more sustainable than another. In this paper, a new model for the sustainability in the machining field is proposed with the goal to increase productivity, reduce ...

Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

Halliburton Co. and Schlumberger Ltd., trying to forestall a regulatory crackdown that would cut natural-gas drilling, are developing ways to eliminate the need for chemicals that may taint water supplies near wells. At risk is hydraulic fracturing, or fracking, a process that unlocked gas deposits in shale formations and drove gains in U.S. production of the fuel. Proposed regulations might slow ...

As U.S. oil and gas production increased this past decade, so, too, did spills of salty oilfield wastewater that can foul the land, kill wildlife and threaten freshwater supplies. An Associated Press analysis of 11 states found more than 180 million gallons of wastewater spilled from 2009 to 2014. Questions and answers about this damaging byproduct of energy production: WHAT IS IT? ...

Mark Zwinderman of Surface Active Solutions, looks at the dangers involved in the cleaning and maintenance of mud tanks and associated equipment The oil industry involves many thousands of people working daily in potentially hazardous circumstances with dangerous chemicals and sophisticated engineering equipment. There has been a consistent and determined drive by the industry to reduce the ...

As U.S. oil and gas production increased this past decade, so, too, did spills of salty oilfield wastewater that can foul the land, kill wildlife and threaten freshwater supplies. An Associated Press analysis of 11 states found more than 175 million gallons of wastewater spilled from 2009 to 2014. Questions and answers about this damaging byproduct of energy production: WHAT IS IT? ...

Reclamation and reuse of unconventional wastewater sources for plant raw water, cooling water and process pre-treatment has increased substantially due to increases in the cost of drinking water, recurring water shortages that can impact business operations, and tightening government regulation. Water is required in almost every industrial sector for the processing and manufacture of products. ...

Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

When oil prices were 80 to 100 dollars per barrel, water management costs were high, but they were tolerable when money was flowing profitably. However, as today’s falling price nears 40 dollars, water related costs are still high and only exacerbate widespread industry losses. The 150 US-based companies tracked by Oil & Gas Journal and Oil & Gas Financial Journal reported that ...

As large generators of oily wastewater tighten effluent controls, the U.S. Environmental Protection Agency (EPA) is targeting smaller generators. Some of the firms receiving their attention are smaller manufacturing plants, automotive garages, mobile equipment service shops and truck farms. Many of these firms do not have access to a sanitary sewer system that will accept oily wastewater. Because ...

The world’s appetite for fossil fuels is not abating anytime soon, and the alternatives fall short. Nuclear energy makes people uneasy, coal is perceived as not being that clean, hydroelectric requires massive capital outlays, solar is still improving and the wind just doesn’t always blow. For the foreseeable future, North Americans have embraced the idea that expanded production of ...

Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...
